NGC 7026 (Gary Imm)

NGC 7026

This object is a tiny magnitude 15 planetary nebula located 10,000 light years away in the constellation of Cygnus at a declination of +48 degrees. The PN is only 40 arc-seconds long. It is the typical PN size of 2 light years.

This object has 2 nicknames. The first is Burhham's Nebula, named after its discoverer in 1873, Sherbourne Wesley Burnham. He discovered it at Northwestern University in Evanston, Illinois, my alma-mater. The second nickname is the Cheeseburger Nebula. I assume that in the eyepiece it looks more like a cheeseburger than it does in this image. The cheeseburger was invented 50 years after the discovery of this nebula.

I love this object because it is an excellent example of a multipolar PN. Our view is side-on, which gives the best view. The constricting torus is seen here in cross-section as two vertical white sections left and right of the central progenitor star. This central star is visible but pales in comparison to the nearby 10th magnitude orange star (TYC 3592-2787-1) adjacent to the nebula. The 2 primary lobes extend up and down from the central star. As seen in the Hubble image, unlike the typical bipolar hourglass shape, this is a multipolar PN with some other lobes visible.

I imaged this object 3 years ago with my Tak 130 and I was never happy with the result. That image has now been deleted from Astrobin. However, the stars from that effort were better in quality than this recent imaging effort, so this image combines a new image of the nebula with the RGB stars from the old image.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
